Slavonia

Slavonia is one of the four historical regions of Croatia, located in the east of the country. The largest city in the region is Osijek, followed by Slavonski Brod and Vinkovci; it is located along the Pannonian Basin, and it borders the Danube, Drava, and Sava rivers and their valleys. Ostrogoths and Lombards controlled the region until the arrival of the Avars and the Croats, and the Principality of Pannonian Croatia was established there. After the fall of the Kingdom of Croatia, the region would be ruled by Hungary, and the Ottoman Empire ruled Slavonia from 1552 until the Austrian Empire conquered it in 1699. Slavonia would become a part of Yugoslavia in 1918 after the end of World War I and the partitioning of the Austro-Hungarian Empire, and the region would finally take its modern form under Croatia upon the breakup of Yugoslavia in 1992. In 2011, the region had a population of 806,192 people.
